Testing source code program with 0install

Hello

I have a program, for example:
int main() {}
, that I'd like to test by compiling it using several compilers and 
compiler flags. Can I use 0install to automatically compile and run the 
program using all permutations of e.g. "CC = gcc4 gcc5 clang35 clang36 
icc14 icc15" and "CFLAGS = -Os -O0 -O1 -O2 -O3"? The program would also 
have dependencies that I'd like to be compiled with same CC as the program.

Should I make each CC into a separate interface required by the program 
(and its dependencies) that only injects some value for CC into the 
environment and similarly for CFLAGS? I could also create separate 
executables from the same source with different compiler flags but the 
same would have to be done for each dependency also which would 
duplicate a lot of interface code. Are there any other options for doing 
this?
Thanks

Ilja
